Allow your users (except for administrators) to manually delete their own accounts. It uses the <a href="http://t4t5.github.io/sweetalert/" rel="nofollow ugc">Sweet Alert</a> jQuery plugin for slick-looking alerts and prompts.
By default, this plugin adds a button to a user’s profile page in the wp-admin. You can also add a delete button to any page or post using the <code>[wp_delete_user_accounts]</code> shortcode.
NOTE: Delete buttons are not displayed when logged in as an administrator. This is done to protect against locking yourself out of your site. To see the delete button, you’ll need to log in with an account that does not have the administrator role.
For more technical info, including available hooks (actions and filters), please see the plugin’s <a href="https://github.com/renventura/wp-delete-user-accounts" rel="nofollow ugc">readme file on Github</a>.

The Limit Access WP Plugin is a simple plugin that limits the number of IPs that can be accessing an account at the same time.
Eg. If $allowedIPs is set to 3, the account “JohnDoe” can be logged into from three separate IPs. When the the account is accessed the fourth time, the user will be logged out and redirected to a custom page made by you.
If you have any questions or problems with the plugin, please let me know!
